Since you are a navy nuke, you'll love this example:
A first class nuke-MM I worked with got a flat tire. He called a buddy off the ship to come get hime, then sat against a post to wait. He fell asleep, and was awakened by repeated kicks to his gut. He had no idea who was attacking him until he felt the cuffs go on. Racist cops in Agana Guam decided to have some fun with a white sailor. They took him to a building, cuffed hiim to t chair, beat him bloody, then rubbed pepper-spray in his wounds until he was screaming. Then they charged him with resisting and the usual crap.
He went to the JAG when he was taken back to the ship, but they gave him zero support. In fact, he was branded a troublemaker. He was a damn good petty officer and MM.
Sure, everyone who gets arrested deserves what they get.
And your story? It's the military equivalent of an urban legend. It's been told, re-told, and has mutated over time to fit whatever circumstances. I've heard dozens of variations of it. It probably has a kernel of truth, somewhere way back in the mists of time. But still, allow me to trample on it--
#2: If you're dumb enough to fall asleep in a strange place, you may have to deal with some unintended consequences when you wake up. Gasp! Gee, it's not a good idea to fall asleep in the street (or any other strange place)? Whouda thunk it?
I've lived in Japan off and on for a number of years, and been to many other places besides. The rules are: walk the straight and narrow, obey the laws, be nice, spend your money like a good tourist, and nobody will get hurt. Cover your own ass, and no one else will get a shot at it.
#3: Never rely on the JAG for help about anything. Anyone who's ever needed legal help while in the military could have told 'Mr. X' that. JAG and A Few Good Men may have been a couple of good yarns, but that's all they were--fiction. A real JAG couldn't get you off on a parking ticket.
Lessons learned? A little common sense goes a long way. Go to your court-appointed classes. And don't fall asleep on the street in 'Guam.'
